METHOD OF ORNAMENTING AND IMPROVING PREPARED ROOFING.

Application filed September 4, 1912.

1/ 0 all whom it may concern:

Be it known that I. MATHIAS B. BECKER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods of Ornamenting and Improving Prepared Roofing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide an improved method of treating ready roofing for the purpose of ornamenting the surface thereof and improving the structure of the product to cause the same to become more durable.

The invention consists in the several steps of the process hereinafter fully described and particularly claimed.

The invention is preferably carried out by means of a machine, and in the accompanying drawings I have illustrated a machine adapted to the purpose and also the completed roofing after being subjected to the several steps of the said method.

In the accompanying drawings: Figure 1 is a view in elevation of prepared roofing having its surface treated for the purpose of ornamenting and improving the same. Fig. 2 is a sectional view of the roofing on the line 22 of Fig. 1. Fig. 3 is a view inside elevation of a machine adapted for treating roofing in accordance with my invention. Fig. '1 is a similar view of the opposite side of said machine. Fig. 5 is a plan view of the machine. Fig. 6- is a central vertical longitudinal section of the machine on the line 66 of Fig. -45. Fig. 7 is a perspective view of a roller employed in the machine.

My present invention relates to an improvement in the method of treating roofing described and claimed in Letters Patent No. 1024540 issued April 30, 1912, and relates to the production of improved roofing such as is described and claimed in Letters Patent No. 1021550 issued April 30, 1912.

The aforesaid respective patents relate to grit coated prepared roofing which is subsequently treated by covering portions of the surface thereof with a dissolved substance corresponding with that upon which Specification of Letters Patent.

Patented (Int. 26, 1915.

Serial No. 718,459.

the grit is disposed and which serves to cover and embed a part of said grit coating and amalgamate with the surface upon which the grit is carried whereby a roofing is produced which is thicker at some points than at others and in which a part of the grit coating is completely embedded whereas on the other parts of its surface it is only partly embedded.

The objects of the inventions described and claimed in said Letters Patent above referred to were to provide a more ornamental prepared roofing than had heretofore been produced and at the same time to strengthen and improve the structure and wearing qualities of the product.

In carrying out the aforesaid method and producing the aforesaid product the additional coating material is applied so as to produce upon the roofing a design in imitation of a shingle or tile roof or to otherwise give the same an ornamental appearance.

In carrying out the invention described in the aforesaid Letters Patent N 0. 1024549 it was found that the liquid coating when applied in such quantity as to completely embed the grit particles upon which it was applied and penetrating between the same and amalgamating with the grit carrying surface coating, could not be prevented from flowing beyond the area upon which it was intended to be applied so that instead of producing a sharply defined design or configuration on the roofing the flow of the liquid beyond the area upon which it was applied caused the entire design or configuration to become irregular and smudged.

The primary object of the present invention is to provide means whereby such flow of the liquid after application to the roofing is prevented.

A further object of the invention is to ap ply to the added material applied to the grit coated surface of the roofing grit particles of a color contrasting with the general color effect of the primary grit coating whereby the ornamental effect heretofore carried out by the contrasting color effects of the grit coating and the design producing material is carried out by grit coatings of contrasting colors.

To this end the present invention consists particularly in thickening the liquid after application upon the surface of the roof to prevent flow thereof and thus to produce a well and sharply defined design or configuration on the roofing.

The invention consists broadly in applying a granular material upon the surface of the roofing immediately after the application of the liquid thereto, which said material is adapted to become embedded in said liquid and thereby to thicken the latter to prevent flow thereof.

The invention consists further inremoving from the surface of the roofing all of the granular or pulverulent material applied thereto which is not embedded or held thereon by the applied liquid. I

The invention consists further in applying to the liquid a granular or pulverulent material of a different color from that of the grit coating of the roofing and which, preferably, corresponds in color with the liquid applied for the purpose of ornamenting the surface whereby the contrast in color requisite to the attainment of the ornamental efl'ect is maintained.

' The roofing as prepared, prior to its treatment for ornamentation, consists, usually, of a web of felt or other fibrous material which is immersed in and passed through a receptacle containing boiling asphaltum and which, as it leaves said receptacle, is passed under a suitable sanding device whereby grit is distributed upon at least one face of said roofing; said grit being distributed over said surface while the latter is still hot and soft whereby it becomes partially embedded in said surface. This roofing is then cut into lengths and rolled up where-- upon it is ready for market. The entire surface of this roofing is, however, of a uniform color and appearance and presents a rather monotonous appearance on a roof. Furthermore, the grit coating is usually carried away in a relatively short time by ice and snow in the Winter time and also by heavy rains, wind storms and the like.

In order to give the roofing a very ornamental and artistic appearance and at the same time to protect the grit coating thereof against the action of wind, rain, snow and ice, I apply upon portions of the coated surface, in such spots or along such lines as will produce on said surface a regular design or configuration in imitation of shingles, tiles and the like, a liquid coating of dilute asphaltum, or the like. v 'This coating applied over the grit consists preferably, of asphaltum diluted with creosote, benzin or other known volatile solvent for asphaltum and is applied in such quantity as to flow through the grit coating upon the lower coating which is then partially dissolved thereby and becomes amalgamated therewith so that as the last applied coat dries and hardens it becomes homogeneous with the lower coating and completely embeds the grit particles over which it was applied. This added coating material produces ridges or ribs or other elevations upon the roofing which project through and above the grit coating thereof so that the portions of thelatter which are not covered are contained in hollows bordered by said ridges or ribs and are thereby protected largely from the action of the elements which tend to loosen said grit and cause it to leave the roofing. The liquid so applied, however, must necessarily be applied in relatively large quantities or thick layers in order to produce a ridge or rib of the depth necessary to embed the grit coating and such liquid when applied will obviously continue to flow upon the lower coating until it has attained a degree of viscosity whereby such fiow will be prevented. Thus the configuration or design is rendered irregular and blotchy. To obviate this difiiculty I apply upon the surface of the roofing, after applying the second or ornament: ing coating thereto, and while the latter is fluent a granular material preferably consisting of sand which is finer than the grit coating of the roofing and in such manner as to cause the same to become embedded in the liquidcoating last applied thereby immediately thickening the same and increasing its viscosity to a degree which will prevent fio-w thereof and which, when said liquid has hardened, gives it a rough weather resisting surface besides increasing its depth, and causes it to project to greater height over the primary grit coating whereby its protective qualities are further increased. That portion of the last applied sand or other finely divided material which is not absorbed or partially absorbed by the liquid coating last applied is shaken from the surface of the roofing in any suitable manner.

In Figs. 1 and 2 I have illustrated roofing made in accordance with the aforesaid method and in which A indicates the web of fibrous material, such as woolfelt, or the like, and B and C. the coatings of asphaltum. Upon one of said coatings, such as B, there is applied in the manufacture of the roofing, grit particles D which become partially embedded in and adhere to said coating B. Parts of said surface are then given a coating E of dilute asphaltum which covers some of the grit and flows through the latter and amalgamates with the coating B. Immediately after applying said coating E and while the same is fluent I apply thereto a coating F of sand or other grit particles which may be substantially pulverulent or relatively coarse and which becomes embedded or partially embedded in said .coating E thus immediately" thickening the latter and preventing spreading of the same beyond the edges of the portions of the surface upon which it has been applied and which, furthermore, fills the same up so as to produce higher ridges or ribs on the surface B than would result from the application of the liquid only.

In carrying out the method the prepared roofing is passed through a machine which is in some respects similar to a cylinder printing press and wherein the coating E is applied to the surface or coating B and over the grit coating D. The said machine comprises a suitable frame-work in which there is rotatably mounted a drum 1 Which is mounted upon a shaft 2 journaled in bearings carried by said frame. Above the said drum 1 is a second drum 3 mounted upon a shaft 4 journaled in bearings carried by members 5 pivotally secured at one end to the frame by means of hinges 6, or the like, the other ends of said members 5 receiving the threaded end portions of rods 7 pivotally secured to a rigid member 8 of the frame. The said rods receive fly nuts 9 b means of which said member 5 may be forced downwardly to cause the drum 3 to bear upon the surface of the drum- 1. On the shaft 2 of the drum 1 there is mounted a spur gear 10 which meshes with a spur gear 11 on a shaft 12 which carries the pulley 13 Which is geared by means of the belt 14 to a source of power. The said shaft 12 constitutes the drive shaft of the machine and carries 5 rocket wheels 15 and 16 respectively.

ver the former there is trained a sprocket chain 17 which engages With the sprocket wheel 18 on a shaft 19 which carries What I will term the printing roll 20, said chain 17 being further trained over a sprocket Wheel 21 mounted on an idle shaft 22 journaled in bearings carried by the frame-piece 8. The shaft 19 passes through the end walls of a tank 23 adapted to contain the coating material in liquid form. The latter may be maintained hot Within said tank by means of the steam circulating pipes 24 disposed within the latter. The drum 20 is maintained partially immersed in the liquid contained in said tank 23 and the ribs 25 extending longitudinally and circumferentially of said drum are adapted to carry the same upwaiflly and in contact with the roofing to apply the same thereto as Will hereinafter more particularly appear. Disposed above the drum 20 is a drum 26, the

trunnions of which are journaled in bearings .carried by arms 27 pivotally secured at one end to the members 5 carrying the bearings for the shaft 4 and which at their other ends are adapted to rest upon supports 28 carried by the frame-pieces 8, said drum 26 being adapted to rest upon the roofing and force the same into contact with the surface or ribs of the roller or drum 20. The free end portions of the arms 27 are adapted to be adjusted in elevation by inserting between the same and said supports 28 blocks or wedges 2 in an obvious manner. J ournaled thereof.

in Fig --c--.

in bearings 30 is a shaft 31 which carries a pulley 32 over which the belt 14 is trained for the purpose of rotating said shaft. Said shaft carries a plurality of radially disposed arms 33 in which rods 34 are mounted, the latter being adapted, during rotation, to strike the under surface of the roofing to agitate and vibrate the latter.

The roll of roofing is adapted to be mounted upon a shaft 36 removably mounted upon the frame contiguous to one end The roofing is then passed between the drums 1 and 3 and then between the drums 20 and 26 and is then passed over an idle roll 37 disposed at the other end of the frame of the machine. It is thence passed upwardly at an incline over another idle roll 38 and then over the drum 3 to a delivery carriage 39 which carries the treated roofing to a point at which it is again rolled up ready for market. The said delivery device 39 consists of an endless belt carrier trained at one end over the sheaves or pulleys 40 carried by the shaft 41 which is driven by means of the sprocket wheel 42 and sprocket chain 43, the latter being trained over the sprocket wheel 16 on the sections 44 being maintained'normally concentric with the shaft 4 by .means of radially disposed compression springs 45 bearing at one end on the shaft 4 and at their other ends upon the interior of each of said sections 44 in a well-known manner, as shown The bearings for said shaft 45 are forced downwardly toward the drum 1 by means of the members 5 and fly nuts 9 on the rod 7, as will be obvious, thus causing all of said sections 4.4 to become more or less ecc'entrically disposed relatively to the shaft 4 against the action of the springs 45 whereby each one of them exerts a yielding pressure upon the surface of the drum 1 and upon the roofing passing between the drum 3, composed of said sections, and said drum 1. The said sections 44 thus bear upon what is normally the under surface of the roofing and thus compresses the upper or grit coated surface upon the drum 1 whereby the grit is forced farther into the coating B of the roofing before the latter passes between the drum 26 and the printing roller 20. as will be obvious.-

The printing rollers 20 carries the liquid, contained in the tank 23 upwardly and ap plies it to the grit coated surface of the roof ing which is disposed downwardly. The said liquid adheres to the grit particles and is slightly viscous so that it will not flow too readily and will not drip after being applied to the grit coated surface. After the roofing. passes over the idle roll 37 the printing surface is reversed in position and disposed at an incline and in passing between the rollers 37 and 38 itpasses underneath the sanding box or hopper TS in the bottom of which are a plurality of openings l7 controlled by a slide valve 48 and through which sand or other granular or pulverulent material flows upon the printed surface in an obvious manner. The fiow of said sand or other substance is continuous upon every portion of the surface of the roofing passing underneath said box 46, and by means of the rods 3i said sand is caused to flow downwardly toward the roller 37 and the surplus thereof which is not absorbed or held by the liquid applied by the roller 20 is delivered upon the floor or into a suitable receptacle disposed to receive the same. The roofing then passes again over the drum 3 and becomes deposited upon the belt 39 which serves to carry it to a convenient point where it may be rolled up again preparatory to marketing the same. The sald roller 20 may have longitudinal and circumferential ribs and projections, such as are herein illustrated, whereby an imitation of a shingle roof is produced, or said ribs may be designed to produce any desired design or configuration on the surface of the roof. Said printing roll may be made of any suitable material. though I have found that metal is most satisfactory.

It "will be understood, of course, that my invention is not limited to the use of the particular materials herein mentioned as the hereindescribed method applies to all ma terials suited to the purpose and consists broadly as defined in the appended claims, in appl ing upon a face or surface of prepared roofing an added liquid coating adapted to harden and to produce an appreciably elevated design or configuration in a dif ferent color on said roofing, and preventing flow of said liquid by adding thereto a granular or otherwise finely divided solid to immediately thicken it so that it becomes practically non-fluent.
